' To all whom it my l Beit known-that I', JoHN M. Ps'rrnnson, a

citizen of the United States residingat La Fayette, n=` the county ofallier and State of Georgia,`have invented a new and usefulWrigley-Shade, of which the. following is a specification.

v invention relates to window shades and its object is to rovide meanswhereby the shade can be eit er raised from the bottom or lowered fromthe top of a Window, or both raised from the bottom and lowered frorntheto at the same time, means being Y 'rovided'whereby the shade rean be4eldin any position to which it may be a justed.

-f A further object is to provide brackets of novel form for use inconnection with the shade fixtures and whereby curtain poles can beconveniently suppo l With these and other objects in-view the inventionnconsists of certain novel features ofi construction and combinations ofparts whichwill be hereinaftermre fully described and' pointed out inthe claims.

Fig. 5 is a front view of one of the brackets -of Refs-to the figuresl by characters of reference, i designates a window cas'and arrangedlo 'tu inally nponeachside ereof is a rack referabl formedof an elonated at meta stri c ped transversely to orm teeth althoug itis to be understood from either end, novel the rolltimes in in lieuofthe strip 1. Each strip 1 extends throughout the height' ofthe windowcas' and arranged at the lower end of each strip 1s an outstandingL-shaped bracket 2 having a slot 3 therein or the reception of a ton e 4extending from and formed at one en of a guide or retaining bar 5Y arrad parallel and in front of the adjoining strip 1.

This bar is referably in the form of a dat strip of meta increasing inwidth toward the center thereof. The upper. end of the bar extends n'toa slot 6 formed in a bracket T secured to the top ortion of the windowcasing and this bracket as a laterally exten inverted U-shaped extension8 in whic Y is mounted a sheave 9. A retain' clip 10 is pivoteduponfthe-bracket 7 and isnisposed to swing laterally so as to overba?and bear u` on the upper end of bar 5 or to e swung in t e o positedirection so as to uncover the end o `said bar.

Each rack 1 is engaged by a gear 11 hav' flanges upon the faces thereofand entending beyond the teeth, said flanges being indicated at 12 anddesigned toV extendf across opposite faces of the rack and of theadjoining retaining bar. The two gears 11 are connected by a roller 13having hooks 14 thereon designed to detachably engage the up r endportion of a flexible curtain 15. Aium lissecuredu ntheouterfaceof oneof the ars 11 anlinhas'a cord or other flexible device 17 fastened to itand exten u ward over the sheave thereabove an t ence downward to thebottom of the window casing'.

Arranged below the respective racks 1, 1 are gears 18 each hav'- inannular flanges extending to opposite si es of the adjoining racks andret bars and these ears are secured to the ends o; a roller 19 to w 'chthe lower end of the shade fixture is fastened. A drum 20 is securedtothe outer face of one of these gears and has a cordor other flexibledevice connected the1eto and extending upwardly to and over the othersheave of the xture 1t being understood, of tom-se, that the imm-s- 16and 20 :ocated at opposite sides of the window e. Secured to the windowcasing at each slide of the opening therein is a clip for holding theadjoining cord in shifted sition. Ecc clip consists of a forked bo g' 22of spring metal secured at its ends to t e casing while a head 23substantially V-shaped, extends from this body and has a linger piece 24at the end thereof so that it can be convenientcly manipulated. Eachcord 17 and 21 exten s through the fork of one of these clips and isdesigned to be pressed against the casing by the head 23. n orderhoweverI that the head may bedprevented from pressing too far into thecor and thus injuring it through gears 11 and upon the4 lib:

What is claimed is:

1. The combination with parallel racks, brackets adjacent the endsthereof, and combined guide and retaining devices detachably supportedby the brackets; of

rollers arranged one above the other, a shade secured at its endsthereto, gears upon each roller and interposed between the racks andretaim devices, a drum upon each roller, and flexible means for rotatingeach drum to shift it vertically.

2. In a shade fixture the combination with a rack and slotted bracketsoutstanding from the ends thereof; of a retaining bar seated at its endswithin the slots and parallel with the rack, said bar bearing upon thelower bracket and a retaining clip movably mounted upon the otherbracket and normally bea u on the end of the bar.

3. In a s e fixture the combination with a rack and su rposed slottedbrackets ad] acent the ends t ereof; of a retaining bar having its up erend seated within the slot xn the upper racket, there beinga tongue atthe lower end of the bar and seated in the slot in the lower bracket,and a shiftable retaining clip upon the up bracket and bearing upon theend of the ar.

4. In a shade fixture the combination with a bracket having an invertedU-shaped ezctensip'n, and a sheaige whintthe extenlgi; o apoesup ortracet, a` a y strip, there ingminwardly drebll means upon said strip forembracing and frictionally engaging opposite edges of the invertedextension.

5. The combination with parallel racks and brackets secured adjacent theup er and lower ends of the racks; of eombin guide and retaining devicessup rted by the brackets and parallel with t e reeks, upper and lowerrollers, a shade seeuredjat its ends to, and disposed to he wound uponboth of the rollers, gears carried b the rollers, and mounted to travelupon t e rac-lcs and tween the racks and retainix strips, a drum uponone end of each ro er, lexible actuating devices connected to anddisosed to be wound Aupon the res ctive drums, and guide wheels carriedy the upper brackets and supporting said liexilvle devices.
